Flextech Television Network was a channel from Flextech (later to became Virgin Media Television) that was a showcase to programmes from the company's other channels - Bravo, Challenge, Living and Trouble. Broadcast from 2003, it was replaced by Virgin 1 on 1st October 2007.
Launched in October 2002, UK History was the precursor channel to today's Yesterday. In March 2004, the channel was rebranded 'UKTV History'.
Unfortunately, this is a classic example of a mistake still being made today by the companies that create presentation, in not understanding that what may look good at the design stage and during production, does not stand up to digital compression - especially on DTT.
